[0051] DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
Definitions
[0052] For purposes of the present disclosure, it is noted that spatially
relative terms, such as
"up," "down," "right," "left," "beneath," "below," "lower," "above," "upper"
and the like, may
be used herein for ease of description to describe one element or feature's
relationship to another
element(s) or feature(s) as illustrated in the figures. It will be understood
that the spatially
relative terms are intended to encompass different orientations of the device
in use or operation
in addition to the orientation depicted in the figures. For example, if the
device in the figures is
turned over or rotated, elements described as "below" or "beneath" other
elements or features
would then be oriented "above" the other elements or features. Thus, the
exemplary term
"below" can encompass both an orientation of above and below. The device may
be otherwise
oriented (rotated 90 degrees or at other orientations) and the spatially
relative descriptors used
herein interpreted accordingly.
Description of Selected Specific Embodiments
[0053] Various embodiments of the present general inventive concept, as
described herein,
provide an animal tracking and control apparatus having a tracking unit to
track an animal, and a
stimulus unit to provide a stimulus to the animal. The tracking unit and
stimulus unit are
configured to be removably coupled together. In other words, the tracking unit
and stimulus unit
are formed such that the two units are able to be docked together. The
coupling of the two units
as modules may be referred to interchangeably throughout this description as
docking.
[0054] The tracking unit and stimulus unit may transmit and/or receive
signals to/from a
common control device. In the various embodiments described herein, the
control device is
described as a remote handheld control device, or more simply a handheld
transceiver. The
single handheld transceiver communicates with both the stimulus unit and the
tracking unit, and
may send/receive signals to/from the units using different channels or
different ID codes. Also,
it is understood that the control device is not limited to any ornamental
features shown in the
handheld transceiver described in the drawings.
Page 7
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
[0055] The animal tracking and control apparatus may be provided to any
animal, but is
typically described herein as being provided to a dog. For example, the animal
tracking and
control apparatus may be secured to an animal encircling device such as a dog
collar which is
worn by a dog, in order to track the dog's movements and provide a control
stimulus to the dog.
This is merely one non-limiting example of how the animal tracking and control
apparatus may
be utilized.
[0056] In an example embodiment in which the animal tracking and control
apparatus is
secured to the animal by an animal encircling device, such as a dog collar,
either the tracking
unit or the stimulus unit may be secured to the dog collar, and the other of
the tracking unit or the
stimulus unit is removably coupled to the unit secured to the dog collar. As
an example, if the
tracking unit is secured to the dog collar, the stimulus unit may be removed
so that only the
tracking unit is provided to the dog wearing the dog collar. Further, the
animal tracking module
may be provided with a cover to be removably coupled to the tracking module in
lieu of the
stimulus unit being in a coupled configuration.
[0057] In the examples illustrated and discussed throughout this
description in which the
animal tracking and control apparatus is secured to an animal encircling
device such as a dog
collar, the tracking unit is described as being secured to the dog collar. The
dog collar is secured
to the tracking unit by securing members such as screws, a molded collar that
is permanently
fastened to the tracking unit, a pass through woven collar, an attached woven
collar, or a pass
through molded collar.
[0058] The animal tracking unit may operate similarly to a typical Global
Navigation
Satellite System (GNSS) device. Various GNSS tracking systems, which employ
GNSS systems
such as the Global Positioning System (GPS) of the United States, the Russian
GLONASS, etc.,
have been typically used to monitor the movement of a mobile subject such as
an animal, often
relative to a selected containment area. In such systems, the position and
speed of the animal are
monitored through the use of the GNSS satellites, and the position and speed
of the animal may
be displayed on a monitoring device. If a containment area is also employed,
the containment
area may also be displayed on the monitoring device.
Page 8
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
[0059] The animal stimulus unit may operate similarly to various animal
control apparatuses.
For instance, the animal stimulus unit may provide the animal with various
stimuli such as
vibrations, sound or spray. Further, these various stimuli may be selectively
provided to the
animal, and the levels of the various stimuli may be adjusted. For example, a
vibration provided
to a dog to control a certain behavior may be increased if the dog does not
respond to the
previously used level of vibration stimulus. The animal stimulus unit may be
provided with one
or more protrusions to extend toward the animal's skin to make contact through
the coat.
[0060] The previously described control device may be a handheld
transceiver which
sends/receives signals to/from the animal tracking module and stimulus module,
and may have a
display such as a graphic user interface (GUI) which may show the location of
one or more
animals equipped with the tracking module.
[0061] The handheld transceiver may have a plurality of controls to allow
various operations
such as switching the display emphasis between various hunting dogs being
tracked and
providing various stimuli levels to different dogs. The handheld transceiver
may communicate
with the tracking module using a different channel than the one used to
communicate with the
stimulus module.
[0062] Thus, an integrated animal tracking and control system provides a
user or owner with
an animal tracking or animal tracking/training system that can be user
configured. In any of a
number of example configurations, there is only one collar (or other animal
encircling device)
mounted device which is provided to the animal, and only one remote handheld
control unit.
The collar mounted device may under one embodiment include both the tracking
unit and the
stimulus unit in a configuration in which those units are docked together, and
includes only one
of the units in a configuration in which the units are not docked together.
Such an apparatus and
system greatly simplifies the mounting and operation of an animal training
and/or tracking
system. Such an apparatus and system also allows the sporting competitor to
readily remove the
training module for competition.
[0063] Figure 1 is a perspective view of an animal tracking unit 10 as may
be used in the
modular dog collar of the present invention, in one embodiment. The
illustrative tracking unit
Page 9
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
includes a receiving portion. The tracking unit 10 may receive GNSS signals
and transmit
position signals to a control device. In this example embodiment, the tracking
unit 10 is
provided with receiving portion 12 configured to receive a stimulus unit (see
Figure 2, 20) to be
removably coupled to the tracking unit 10. In this example, the receiving
portion is configured
so as to form a dovetail connection with the coupled stimulus unit 20. It is
understood that the
dovetail connection is merely one configuration by which the tracking unit 10
will be docked
with the coupled stimulus unit 20.
[0064] The tracking unit 10 of this example embodiment is also provided
with holes 14 to
receive screws to further secure the coupled stimulus unit 20 to the tracking
unit 10. Although
screws are described in this example embodiment, any type of adhesion member,
such as bolts,
brackets, clamps, and so on, may be used to further secure the coupled, or
docked, units. Also, in
other example embodiments, no adhesion members may be used to further secure
the docking of
the units. It is understood that the shape and dimensions of the tracking unit
10, as well as the
other example units illustrated in the following drawings, are merely simple
examples for
illustrative purposes, and corresponding units in various embodiments of the
present general
inventive concept may vary widely in size, shape, composition, and so on.
[0065] The tracking unit 10 may further be provided with an antenna 60 (as
described later in
Figure 6) or antennas (not shown) to transmit/receive GPS signals and/or
signals to the control
device. The antenna(s) may be integrated with an animal encircling device to
which the tracking
unit 10 is secured.
[0066] Figure 2 is a perspective view of an animal stimulus unit 20 as may
be used in the
modular dog collar of the present invention, in one embodiment. The
illustrative stimulus unit
includes an extending portion configured to engage the receiving portion of
the animal tracking
unit. The stimulus unit 20 may receive control signals from the control device
which also
communicates with the tracking unit 10 in order to provide a stimulus to the
animal. In this
example embodiment the stimulus unit is provided with an extending portion 22
configured to
slide into the receiving portion 12 of the tracking unit 10 in order to dock
the stimulus unit 20 to
the tracking unit 10 with a dovetail connection. It is understood that either
of the tracking unit
or the stimulus unit 20 may be provided with the receiving portion 12, with
the remaining one
Page 10
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
of the tracking unit 10 or the stimulus unit 20 being provided with the
extending portion 22.
Also, the coupling of the units may be achieved through configurations other
than a receiving
portion receiving an extending portion, and/or other than a slidable
connection as illustrated in
these drawings.
[0067] The stimulus unit 20 of this example embodiment is provided with
through holes 24
through which screws may pass to further secure the docking of the tracking
unit 10 and the
stimulus unit 20. The screws, or other adhesion members, pass through the
through holes 24 to
the holes 14 of the tracking unit 10.
[0068] The stimulus unit 20 of this example embodiment is also provided
with protrusions
26 which extend from the stimulus unit 20 to contact the skin of an animal and
provide a
stimulus, such as a vibration. The level of the stimulus may be adjusted
through the control
device communicating with the stimulus unit 20. The stimulus unit 20 may
further have an
antenna (not shown) to be used in transmitting and/or receiving control
signals from the control
device. It is understood that the protrusions 26 are merely an example of how
the stimulus may
be delivered to the animal.
[0069] Figure 3 is a perspective view of the animal tracking unit 10 and
animal stimulus unit
20 from Figures 1 and 2. Here, the animal tracking unit of Figure 1 and the
stimulus unit of
Figure 2 are seen in exploded apart relation. As illustrated, the extending
portion 22 of the
stimulus unit 20 slides into the receiving portion 12 of the tracking unit 10
to form a dovetail
connection. After the docking is achieved, screws 30 may be screwed into the
holes 14 of the
tracking unit 10 through the through holes 24 of the stimulus unit 20 in order
to further secure
the docking of the units.
[0070] Although not illustrated in these drawings, each of the tracking
unit 10 and the
stimulus unit 20 may be provided with on/off buttons, on/off indicators,
charging jacks, and
other similar features typically provided to electric/electronic devices.
Also, the stimulus unit 20
may be provided with an internal or external antenna to be used in
communication with the
control device, and the tracking unit 10 may be provided with one or more
internal and/or
external antennas to be used in communication with the control device and/or
GNSS satellites.
Page 11
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
One or more of the various antennas may be integrated with or supported by an
animal encircling
device to which the animal tracking and control apparatus is attached. These
features have
largely been omitted from the drawings to present a more clear illustration of
the docking feature
of the units.
[0071] Figure 4 is a perspective view of the animal tracking unit 10 of
Figure 1. Here, the
tracking unit 10 is ready to receive a removable cover 40, shown in exploded
apart relation. The
cover 40 is provided with an extending portion 42 that corresponds to the
extending portion 22 of
the stimulus unit 20, and which slides into the receiving portion 12 of the
tracking unit 10 to
form a dovetail connection in the same manner as that formed between the
tracking unit 10 and
the stimulus unit 20. The cover is also provided with through holes 44 through
which the screws
30 may be screwed into the holes 14 of the tracking unit 10 to further secure
the cover 40 to the
tracking unit 10.
[0072] Figures 5A through 5C illustrate the docking of the stimulus unit 20
to the tracking
unit 10 while fixed to an animal collar 50. These drawings are highly
simplified in order to
illustrate an "outside" view of the tracking unit 10 and stimulus unit 20 as
provided to the animal
encircling device (or collar or harness) 50 so as to be mounted on an animal.
In Figure 5A, the
tracking unit 10 is fixed to the animal encircling device 50, an example of
which may be a dog
collar. The tracking unit 10 may be fixed to the dog collar 50 in any number
of ways, and may
be permanently or removably fixed to the dog collar 50.
[0073] Figure 5B is a simple "outside" view of the stimulus unit 20, the
"outside"
orientation indicating the view from directly outside portions of the dog
collar 50 adjacent to the
tracking unit 10 in Figures 5A and 5C. In other words, the "outside" view is
that of one looking
at a dog wearing the dog collar 50.
[0074] Figure 5C illustrates the stimulus unit 20 docked to the tracking
unit 10.
[0075] Figure 6 is a perspective view of a portion of a modular dog
tracking collar 50 of the
present invention, in one embodiment. The animal tracking unit 10 is affixed
to a dog collar 50,
but without the stimulus unit. As illustrated in Figure 6, the receiving
portion 12 of the tracking
Page 12
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
unit 10 is located on the inner side of the tracking unit 10, which is the
side of the tracking unit
that is facing the animal, e.g., the dog. The tracking unit 10 is able to
track the dog and
communicate with the control device regardless of whether the stimulus unit 20
is docked with
the tracking unit 10.
[0076] Figure 6 also illustrates an antenna 60 provided to the tracking
unit 10, which has
been omitted from various other illustrated embodiments for the sake of
clarity. As previously
described, the tracking unit may be provided with more than one antenna.
[0077] Figure 7 is a perspective view of the modular dog collar 50 of
Figure 6. Here, the
stimulus unit 20 is shown in exploded-apart relation to the animal tracking
unit 10. As illustrated
in Figure 7, the extending portion 22 of the stimulus unit 20 slides into the
receiving portion 12
of the tracking unit 10 to dock the units in a dovetail connection. Once
docked, the protrusions
26 extend away from the tracking unit 10 and stimulus unit 20 toward the dog
wearing the dog
collar 50.
[0078] Figure 8 is a perspective view of the modular dog collar 50 of
Figure 7. Here, the
stimulus unit 10 has been docked with the animal tracking unit 20, forming an
integral modular
dog collar. As illustrated in FIG. 8, the screws 30 pass through the through
holes 24 of the
stimulus unit 20 to screw into the holes 14 of the tracking unit 10. While the
screws 30 further
secure the docking of the stimulus unit 20 to the tracking unit 10, it is
understood that such
further securing and adhesion members are not required under other various
embodiments.
[0079] Figure 9 is another perspective view of the modular dog collar 50 of
Figure 6. Here,
a removable cover 40 is shown in exploded-apart relation to the animal
tracking unit. As
illustrated in Figure 9, the extending portion 42 of the cover 40 slides into
the receiving portion
12 of the tracking unit 10 to couple the cover to the tracking unit 10 in a
dovetail connection.
The use of the cover 40, in the absence of the stimulus unit 20, provides a
smooth contact surface
to increase the comfort of the dog wearing the dog collar 50.
[0080] Figure 10 is a perspective view of the modular dog collar 50 of
Figure 9. Here, the
removable cover has been docked with the animal tracking unit 10. As
illustrated in Figure 10,
Page 13
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
the screws 30 pass through the through holes 44 of the cover 40 to screw into
the holes 14 of the
tracking unit 10. While the screws 30 further secure the cover 40 to the
tracking unit 10, it is
understood that such further securing and adhesion members are not required
under other various
embodiments.
[0081] Figure 11 is an enlarged partial cross-section of the docked
tracking unit 10 and
stimulus unit 20. A screw 30 is shown securing the two docked components
together. As
illustrated in Figure 11, the screw 30 is extends through the through hole 24
of the stimulus unit
20 to screw into the hole 14 of the tracking unit 10, further securing the
docking of the stimulus
unit 20 and the tracking unit 10. While the screws 30 further secure the
docking of the stimulus
unit 20 to the tracking unit 10, it is understood that such further securing
and adhesion members
are not required under various other embodiments.
[0082] Figure 12 is a view of a control device 120 used to control the
tracking unit and the
stimulus unit of Figure 8, in one embodiment. As illustrated in Figure 12,
this example control
device 120 is a remote handheld control device. The control device 120 is
provided with a
display 122 to display a graphical user interface (GUI), a direction button
124 to interface with
the GUI, a plurality of stimulus buttons 125, a back button 126, a
tracking/training toggle button
127, a GNSS antenna 129, and a control device antenna 128.
[0083] The control device 120 determines a user's location from a built-in
GPS antenna 129.
The built-in GPS antenna receives location updates from a GPS antenna provided
to the tracking
unit 10 to track the location of the animal equipped with the tracking and
control apparatus. The
GPS antenna provided to the tracking unit 10 may be mounted on the dog collar
50. The display
122 may display the user's location, the location of one or more animals
provided with the
animal tracking and control apparatus relative to the user or to a
predetermined area, a list of
options for stimulating the respective animals, levels of stimulation, and so
on. The stimulus
buttons 125 may be used to send a signal to activate the stimulus unit 20 to
deliver a stimulus to
the animal. As previously described, the level of the stimulus is adjustable
through the control
device 120.

[0084] The control device 120 under an embodiment may communicate with the
tracking
unit 10 and the stimulus unit 20 on separate channels in order to minimize
interference between
the respective signals.
[0085] Figures 13 through 16 illustrate various displays and graphical
heading indicators,
which may be shown on the control device 120 of Figure 12 using display 122
according to
various examples. Referring to Figures 13 through 16, the example display
screens 122
provided by the control device 120 include tracking information for three
different dogs, as
generally represented by the display icons corresponding to the current
direction and location of
the animal and/or past locations and directions of the animal. In the example
embodiments, the
animals being tracked are referred to in some of the figures as Ripley, Talon,
and Lulu,
respectively. Note that the present general inventive concept is not limited
to any particular
number of tracked animals. Moreover, although the example embodiments of
Figures 13
through 16 illustrate various different dogs being tracked, the present
general inventive concept
is not limited to any particular number or type of animal.
[0086] Figure 13 illustrates a display screen 122 generated by the control
device 120 of
Figure 12, in one example. In Figure 13, the three different direction
indicator arrows 131, 132,
133 correspond to the current location and direction, or heading, of the
respective animals
relative to the user's position. The cross-hair in the middle of the screen
can be used to represent
the current location of the user, although the present general inventive
concept is not limited to
any particular type of graphical indicators, or icons, to represent the animal
and user. For
example, the graphical representations of the animals could take the form of
an animal-shaped
icon. In various example embodiments, the head of the animal could be used to
indicate the
current direction of the animal, and the body of the animal could be used to
indicate the current
location of the animal based on the current scale of the display screen. The
icons can indicate
whether the dog is running, on point, treed, stationary, barking, and the
like, and the movement
of the user.
[0087] Although the user's location is represented in the illustrated
embodiments as a cross-
hair, it is possible to display the location and heading of the user using any
number of icons, such
as a human figure, arrow, circle, or other icon. The orientation of the
direction arrow (e.g., up,
Page 15
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
down, left right, etc.) can represent the current heading or direction of the
animal and user
relative to one another, and the icons can be color coded so the user knows
which icon
corresponds to each dog by the color of the icon matching the color of the
text.
[0088] The display 122 can include an incremented scale to provide a visual
representation
of the actual distance between the user and the respective animals, and can
display the actual
calculated distances from the user for each animal. The user has the option to
keep the scale at a
fixed distance (e.g., 100 yards), or the user can select Auto where the scale
will automatically
adjust in real time once the animal goes outside the scale. The unit can
periodically check to see
if any of the animals are outside the scale and can zoom to a level where all
the animals are
visible on the screen. If the animal is lost or off-screen, a graphical
indicator, such as an outline
of the icon or a blinking icon representing the animal can be provided to the
user, or a separate
tab can be provided showing the animal's location in relation to the scaled
display.
[0089] In Figure 13, Ripley is represented as 131; Talon as 132; and Lulu
as 133. Ripley
131 is shown located 22.8 yards from the user and provided with continuous
stimulation C4
according to one of the stimulus buttons 125; Talon 132 is shown located 50.8
yards from the
user and provided with vibration stimulation VB according to one of the
stimulus buttons 125;
and Lulu 133 is shown located 6.5 yards from the user with no stimulation
provided. The
stimulation buttons 125 of the control device 120 can be selectively assigned
to each dog,
respectively, and used to provide the corresponding stimulus as desired by the
user.
[0090] The display can include a GPS fix indicator 134, compass indicator
135, and battery
indicator 136. The display can also include separate battery level indicators
137 corresponding
to the battery level of the individual GPS units, respectively. In various
example embodiments,
the GPS fix indicator 134 can indicate whether the control device 120 has
achieved a 'fix' on the
animals as determined by a GPS engine. The compass indicator 135 can indicate
the current
orientation of the control device 120 as determined by the compass unit.
[0091] Figure 14 illustrates another display screen 122 generated by the
control device of
Figure 12, in one example. In Figure 14, similar to Figure 13, the three large
direction
indicator arrows 131a, 132a, 133a correspond to the current location and
direction of the animals
Page 16
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
relative to the user's position. However, Figure 14 includes a plurality of
additional and smaller
indicator arrows 131a, 131b, 131c; 132a, 132b, 132c; 133a, 133b, 133c,
corresponding to a
plurality of historical data points relative to each animal's movement. These
additional data
points are represented in the form of smaller (i.e., subdued) arrows, although
any other shape,
number, and/or size of icons could be used.
[0092] In Figure 14, the smaller historical data points can be displayed in
an incrementally
subdued fashion such that the oldest data point is displayed in a lighter or
fainter strength,
whereas the most current data point is displayed in full strength, to provide
a visual
representation of the historical trail of the animal. Thus, the movement and
data points
transmitted by the first device can be received and displayed by the second
device to provide a
historical mapping as well as current location and direction information of
the animal's
movement relative to the user.
[0093] Figure 15 illustrates another display screen 122 generated by the
control device 120
of Figure 12, in one example. In Figure 15, similar to Figures 13 and 14, the
three large
direction indicator arrows correspond to the current location and direction of
the animals relative
to the user's position. However, Figure 15 includes a plurality of circles
131d, 132d, 133d
corresponding to historical data points relative to the animal's movement.
Although these
additional data points are represented in the form of circles, any other
shape, size, and number of
icons could be used. The smaller circles representing historical data points
can be displayed in
an incrementally subdued fashion such that the oldest data point is displayed
in a lighter or
fainter strength, whereas the most current data point is displayed in full
strength, to provide a
visual representation of the historical trail of the animal. Thus, similar to
the example
embodiment of Figure 14, the movement and data points transmitted by the first
device (or
tracking unit 10) can be received and displayed by the second device (or
control device 120) to
provide a historical mapping as well as current location and direction
information of the animal's
movement relative to the user.
[0094] Figure 16 illustrates another display screen generated by the
control device 120 of
Figure 12, in one example. Figure 16 includes a plurality of circles 131e,
132e, 133e
corresponding to historical data points relative to the animal's movement, but
does not include
Page 17
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
the three large indicator arrows. These historical data points are represented
in the form of
circles, although any other shape, size, and number could be used. In Figure
16, similar to
Figure 15, the smaller circles representing historical data points can be
displayed in an
incrementally subdued fashion such that the oldest data point is displayed in
a lighter or fainter
strength, whereas the most current data point is displayed in full strength,
to provide a visual
representation of the historical trail of the animal. Thus, the movement and
data points
transmitted by the first device (or tracking unit 10) can be received and
displayed by the second
device (or control device 120) to provide a historical mapping of the animal's
movement relative
to the user, with the most recent circle also providing the current location
of the first device.
[0095] In the example embodiments, the change of position between the most
recent data
point and the prior data point can be used to provide a directional vector, or
indicator, indicating
the dog's recent movement. This vector information can be used to graphically
display the dog's
current heading in relation to the user. In the example embodiments, the dog's
current heading
can be indicated by an arrow while the historical location data points are
displayed as dots or
circles, although it is possible that any other shape or number of data points
could be used
without departing from the broader scope and teachings of the present general
inventive concept.
[0096] The user can select to display a complete history of the paths taken
by the respective
animals, a partial history, or no history at all. The historical paths can
take the form of a series of
icons, historical data points, or a continuous path line or bread-crumb trail
to show the path of
the animal over time. For example, if the screen becomes cluttered with
numerous paths, the
user can selectively choose the length of paths shown, or no paths shown. The
handheld control
device can be programmed to automatically refresh the display screen at
predetermined intervals
or lengths of trails to maintain a fresh looking display.
[0097] Figure 17 is a perspective view of a modular dog tracking collar
under an
embodiment. The collar includes an animal tracking unit 10 and docked stimulus
unit 20.
Figure 17 is intended to be a more complete showing of the modular dog collar
of Figure 6. In
Figure 17, the dog collar 50 is affixed to the tracking unit 10 with screws
171. The animal
encircling device 50 may be provided with a loop 172 to secure a positioning
of the antenna 60.

WO 2018/132797 PCT/US2018/013737
[0098] Figure 18 illustrates a view of the tracking unit 10 fixed to the
dog collar 50
according to another embodiment of the present general inventive concept. FIG.
18 is similar to
Figure 6 except that dog collar 50 wraps over the tracking unit 10 on a
surface facing away from
the dog, rather than being fixed to ends of the tracking unit 50 with screws
171 as in Figure 17.
As previously described, any number of collars and methods of fixing the
collars to the tracking
unit 10 may be used.
[0099] Under an alternative embodiment to the animal tracking and control
system described
above, the stimulation unit may be a slave device to the tracking unit. The
alternative
embodiment comprises a stimulation unit/module (hereinafter referred to as a
modular E-collar
unit or stimulus unit) which mates with a stand-alone tracking unit/module
(hereinafter referred
to as a stand-alone GPS tracking unit or tracking unit) to form an integrated
GPS tracking/E-
collar system. As the principle difference from the tracking/control systems
described above, the
E-collar unit is entirely a slave device and has no smart circuitry, no
independent power supply
and no antenna. Accordingly, the modular E-collar unit is dependent upon the
GPS tracking unit
for its power supply, for its general operation and for communication to and
from a remote hand
held control device. The integrated system is further described below with
reference to Figures
19-36.
[00100] Figure 19 is a front view of the integrated GPS tracking/E-collar
system 200. The
system 200 features the GPS tracking unit 202 coupled with the E-collar unit
204.
[00101] Figure 20 is a top down view of the integrated GPS tracking/E-
collar system 200.
[00102] Figure 21 is a side view of the integrated GPS tracking/E-collar
system 200
comprising the GPS tracking unit 202 coupled with the E-collar unit 204.
[00103] Figure 22 is a bottom view of the integrated GPS tracking/E-collar
system 200. The
bottom view as seen in Figure 22 comprises a bottom view of a modular E-collar
unit 204
secured to the GPS tracking unit.
[00104] Figures 23A and 23B are cross-sectional views of the integrated GPS
tracking/E-
collar system 200. Figure 23A is taken across Line A-A of Figure 22, while
Figure 23B is
Page 19
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
taken across Line B-B of Figure 22. Figure 23A shows the power supply 206 of
the GPS
tracking unit 202. The power supply may include a lithium ion polymer battery.
Both Figure
23A and 23B show the stimulus probes 208 extending from the E-collar unit.
Under an
embodiment, the GPS tracking unit 202 receives command signals from a remote
handheld
control unit or transceiver. In response to such signals, the GPS tracking
unit may communicate
with the E-collar unit through the signal contacts (Fig. 24, 216) to initiate
application of a
stimulus to the animal through stimulus probes 208.
[00105] As already noted above, the E-collar unit 204 preferably does not
have its own
firmware or microcontroller or other "smart circuitry." Further, the E-collar
unit 204 preferably
does not have its own battery or other power supply. Still further, the E-
collar unit 204
preferably does not have its own antenna. Instead, the E-collar unit 204
operates essentially as a
slave system dependent on the GPS tracking unit 202 for operation and
communication back to
the hand held device. Note that such handheld device is not shown in Figures
19-33 but is
analogous to the handheld device 120 described in Figure 12 above.
[00106] Figures 19-23 show the E-collar unit 204 secured to the GPS
tracking unit 202.
Figure 24 shows an exploded view of the integrated GPS tracking/E-collar
system. Figure 24
displays the fasteners 210 which pass through holes 212 in the E-collar unit
204 to secure the E-
collar unit 204 to the GPS tracking unit 202. Using the fasteners 210, the
modular E-collar unit
204 may under an embodiment be easily secured to or removed from the GPS
tracking unit 202.
[00107] Figure 24 also shows the signal contacts 216 of the GPS tracking
unit 202. When the
E-collar unit 204 is secured to the GPS tracking unit 202, the tracking side
signal connections
216 couple with the E-collar (i.e. stimulus unit) signal connections (not
shown) and are
surrounded by a water tight seal system which provides a hermetically sealed
communication
pathway between the E-collar unit and the GPS tracking unit. The signal
contacts may be
electrical but embodiments are not so limited. The contacts may comprise pogo
pin or metal
spring connections. As another example, the contacts may comprise an optical
coupling.
[00108] Once the E-collar unit is fastened to the GPS tracking unit, a
microcontroller of the
GPS tracking unit 202 automatically detects that the E-collar stimulus unit
204 has been installed
Page 20
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
and begins to communicate with the unit 204 based on instructions received
from a hand held
control device. A microcontroller (further disclosed in Figure 30 below)
housed in the tracking
unit features a detection pin coupled to the signal contacts of the GPS
tracking unit 202 which
detects the presence of a connected E-collar unit 204 thereby initiating
communication. Due to
the fact that the modular E-collar is a slave device, the GPS unit 202
provides identical tracking
functionality without the E-collar. When the microcontroller of the GPS
tracking unit fails to
detect the presence of a communication coupling with signal contacts of the E-
collar unit, the
GPS tracking unit simply operates as a stand-alone unit without the stimulus
functionality
otherwise provided by the E-collar unit. The easy removal of E-collar stimulus
unit recommends
the unit for use in dog competitions in which competing dogs are not allowed
to wear any form
of stimulus device during competition performances. When the E-collar unit is
disengaged from
the GPS tracking unit, a user of the integrated system may replace the active
unit with a dummy
(or rather inactive) E-collar unit.
[00109] Note that the stimulus applied by the E-collar stimulus unit may be
electrical but
embodiments are not so limited. Under alternative embodiments, the applied
stimulus may be
noise, tone or vibration. Further, when the E-collar unit is disengaged from
the GPS tracking
unit, the tracking unit may not apply any stimulus to an animal.
[00110] Figure 24 also displays a GPS co-axial cable connector 218 and a
radio co-axial
cable connector 220 which respectively couple with a GPS antenna and a radio
antenna. The
GPS antenna and a radio antenna are shown below in Figures 26-28.
[00111] Figure 25 provides another exploded view of the integrated GPS
tracking/E-collar
system. The E-collar signal contacts 222 are seen on the E-collar unit.
[00112] Figure 26 is a side view of the integrated GPS tracking/E-collar
system. The GPS
unit co-axial cable connector 218 is coupled to the GPS antenna 226 using a
GPS co-axial cable
224. The E-collar unit radio co-axial cable connector 220 is coupled to the
radio antenna 228.

system from Figure

[00114] Figure 28 is a front view of the integrated GPS tracking/E-collar
system from Figure
26.
[00115] As indicated above, the GPS tracking unit communicates with a
handheld control
device. The handheld control device comprises under one embodiment a TEK 2.0
handheld unit.
Figure 29 comprises a unit block diagram representing circuitry of a handheld
control device.
The circuitry includes a processor 2902. The processor is coupled to an LCD
display 2904
which presents data and graphics to a user. The processor is also coupled to
an ambient light
sensor 2906. Under one embodiment, the sensor measures ambient light levels of
the device's
environment. The processor may adjust the LCD display back light brightness
based on
measured ambient light levels. The processor 2902 may adjust LCD display back
light
brightness using a power management-integrated circuit 2920.
[00116] The processor 2902 is coupled to memory modules 2910-2916. The
memory modules
include EEPROM (Electronically Erasable Read-Only Memory) 2910. EEPROM
comprises a
type of non-volatile memory used in computers and other electronic devices to
store small
amounts of data that must be saved when power is removed, e.g., calibration
tables or device
configuration. Under one embodiment, EEPROM 2910 stores settings and
calibration data for
the handheld control device. The memory modules also include LPDDR1 2916 which
comprises
low power double data rate synchronous DRAM (Dynamic Random Access Memory).
LPDDR1
2916 provides the processor 2902 a 200 MHz bus for RAM memory usage. The
memory
module also includes an eMMC component 2914. Under one embodiment eMMC
architecture
provides MultiMediaCard flash memory for use in circuit boards as an embedded
non-volatile
memory system. The eMMC component 2914 provides memory for the device's
operating
system, maps and applications under one embodiment. The memory modules also
include uSD
card component 2912. Under one embodiment, a uSD card is removably coupled to
a uSD card
reader. This uSD card may store special maps and files of a user.
[00117] The processor 2902 is also coupled to a user interface 2908. The
interface 2908
includes an On/Off button, switches, a rotary encoder and vibration motor.
Under one
embodiment, a user manipulates the rotary encoder to move one or more cursors
among interface
menu items. Under one embodiment, a user implements switches to make
selections and settings
Page 22

WO 2018/132797 PCT/US2018/013737
for general operation of the device. Under one embodiment, a user manipulates
buttons located
on a side of the device to send stimulation commands to the GPS tracking unit
for
communication to the stimulus unit (E-collar unit 204). The user interface
also includes a
vibration module to provide alarms and warnings to the user.
[00118] The processor 2902 is also coupled to a GPS / GLONASS Module 2928.
The GPS /
GLONASS module comprises a parallel GPS / GNSS receiver with 99 channels for
searching
satellite transmissions and 33 channels for tracking the GPS tracking unit.
The GPS / GLONASS
module is coupled to a dedicated antenna 2930.
[00119] The processor 2902 is coupled to a Power Management Integrated
Circuit (PMIC)
2920. Under an embodiment, power management integrated circuits (power
management ICs or
PMICs) are integrated circuits for managing power requirements of a host
circuit/system. The
PMIC 2920 may include an integrated linear recharger for the Lithium-ion
battery 2922 coupled
to the PMIC. Further, the PMIC regulates all used voltages for the processor
and accessories.
The Lithium-ion battery includes an integrated safety circuit and a Negative
Temperature
Coefficient (NTC) resistor.
[00120] The processor 2902 is also coupled to an Audio Codec module 2924.
An audio codec
is a device or computer program capable of coding or decoding a digital stream
of audio. In
software, an audio codec is a computer program implementing an algorithm that
compresses and
decompresses digital audio data according to a given audio file format or
streaming media audio
format. Under an embodiment, the audio codec 2924 generates sounds and
processes MP3 files.
The audio codec 2924 includes an integrated 1-Watt speaker amplifier.
[00121] The processor is coupled to a Bluetooth module 2932. Bluetooth is a
wireless
technology for exchanging data over short distances. The Bluetooth module
includes integrated
stack software and comprises class 1 and class 2 configurations.
[00122] The processor is coupled to a USB 2.0 connector 2918 for recharging
the battery.
The USB 2.0 connector also provides an interface to external devices.

[00123] The processor is coupled to an RF module 2940 The RF Module
includes a TCXO
32 MHz transceiver. The transceiver integrated circuit (IC) works from an 866
to a 915 MHz
band. The transceiver implements Gaussian frequency shift keying modulation.
The transceiver
module transmits data at a rate of 3000 bit/s. The transceiver module provides
25kHz channel
separation.
[00124] The transceiver IC 2942 is coupled to Surface Acoustic Wave (SAW)
2944, 2946
filters which filter incoming and outgoing transmissions. The SAW filters
reduce spurious
emissions and provide out-of-band interference rejection under one embodiment.
SAW filters
may be dedicated for each frequency band. A power amplifier 2948 amplifies RF
signals from
10-20MW to .5W or 1W. A Tx/Rx RF switch 2952 is integrated into the power
amplifier under
an embodiment. The power amplifier 2948 is coupled to a low pass filter 2954
which reduces
spurious emissions of the power amplifier. The Tx/Rx switch is coupled to a
low noise amplifier
2950 which amplifies received signals via the whip antenna 2956 from the GPS
tracking unit.
[00125] The processor 2902 of the handheld device performs one or more of
the following
functions:

and
[00139] --saves / reads user settings to / from the memory modules 2910-
2916, under an
embodiment.
[00140] As indicated above, the handheld control device wirelessly
communicates with the
GPS tracking unit (and E-collar unit through the GPS tracking unit). Figure 30
shows a block
diagram describing circuitry of the GPS tracking unit under an embodiment.
[00141] As seen in Figure 30, the tracking unit includes a Micro
Controlling Unit (MCU)
3002. The MCU 3002 is coupled to a user interface 3008. The interface 3008
includes an
On/Off button for turning the device on and off Under one embodiment, an LED
light indicates
On/Off status of the tracking unit.
[00142] The MCU 3002 is coupled to an EEPROM (Electronically Erasable Read-
Only
Memory) memory module 3010. EEPROM comprises a type of non-volatile memory
used in
computers and other electronic devices to store small amounts of data that
must be saved when
power is removed, e.g., calibration tables or device configuration. Under one
embodiment, the
EEPROM module 3010 stores settings and calibration data for the tracking unit.

[00143] The MCU 3002 is also coupled to a Power Management Integrated
Circuit (PMIC)
3020. Under an embodiment, the PMIC 3020 may include an integrated linear
recharger for the
3.7V Lithium ion battery 3022 coupled to the PMIC. The Lithium ion battery
includes a safety
circuit and Negative Temperature Coefficient (NTC) resistor.
[00144] The MCU 3002 is also coupled to a buzzer component 3070. The buzzer
component
3070 generates sounds by using a driver circuit.
[00145] The MCU 3002 is coupled to an RF module 3058 which includes
components 3042-
3056. The RF module components are under one embodiment the same as (and
function in a
manner analogous to) the components of RF module 2940 shown in Fig. 29.
[00146] The MCU 3002 is coupled to the E-collar unit 3080. The E-collar
unit applies
harmless electric stimulation to the dog when commands arrive via RF receiver
circuitry of the
tracking unit and are subsequently communicated to E-collar unit. The E-collar
unit applies
harmless vibration to the dog when commands arrive via RF receiver circuitry
of the tracking
unit and are subsequently communicated to E-collar unit.
[00147] The MCU 3002 performs one or more of the following functions:
[00148] --measures tracking unit's navigation coordinates and speed via GPS
/ GLONASS
module, under an embodiment;
[00149] --receives stimulation commands from the handheld device via RF-
transmitter, under
an embodiment;
[00150] --transmits tracking unit's own geological location to the hand
held devices/units in
same group via RF-transmitter, under an embodiment;
[00151] --implements battery recharge control via power management IC,
under an
embodiment;
[00152] --provides two way communication with external devices via USB 2.0,
under an
embodiment;

[00153] --generates audio signals and sounds via buzzer, under an
embodiment; and
[00154] --saves / reads data from the memory 3010, under an embodiment.
[00155] Under an embodiment, the transceiver of the tracking unit's RF
module transmits
signals including positioning date to the remote handheld control device at
defined intervals
ranging from 2.5 seconds to 2 minutes; otherwise the transceiver listens for
command signals
transmitted by the remote device. A command signal may comprise an instruction
to apply
stimulus to an animal wearing the integrated GPS tracking/E-collar system.
[00156] The tracking unit may also include a 3D accelerometer and
magnetometer component
that functions to identify and report a stance or posture of an animal wearing
the integrated
system. For example, a dog on point assumes a different posture than a dog
treeing an animal.
The 3D accelerometer and magnetometer detect the posture and report the
activity to the remote
handheld control unit.
[00157] The tracking unit may also include a bark detection circuitry. The
bark detection
circuitry detects and reports barks per minute to a remote handheld
controller. The bark per
minute metric may be unique to certain animal behaviors. For example, the bark
per minute is
different for a dog that is tracking versus baying an animal. The
microcontroller reports the bark
per minute metric to the remote handheld transceiver. Accordingly, a user of
the integrated GPS
tracking/E-collar unit system may use the bark per minute metric to detect an
activity of the
animal when the animal is neither within visible or audible range of the user.
For example, the
bark per minute metric may indicate the vocalizing of a dog at bay.
[00158] Figures 31-33 show the integrated GPS tracking/E-collar system
under an
embodiment. Note that Figures 31-33 show the integrated system attached to a
collar which may
then be used to mount the system onto an animal. Further, such figures show an
example of a
decoupled E-collar unit next to each integrated GPS tracking/E-collar system.
[00159] According to various embodiments of the present general inventive
concept, an
animal tracking and control system and apparatus (also referred to as a GPS
tracking/E-collar
system and apparatus under an alternative embodiment) provides a user with an
animal tracking,
Page 27
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
animal training, or animal tracking/training system that can be user
configured. In any of a
number of example configurations, there is only one collar (or other animal
encircling device)
mounted device which is provided to the animal, and only one control device to
control the
mounted device. The control device may be a remote handheld control unit. Such
an apparatus
and system greatly simplifies the mounting and operation of an animal training
and/or tracking
system. Such an apparatus and system also benefits the animal provided with
the tracking and
control apparatus, due to reduced bulk and weight resulting from not having to
wear two separate
devices with two separate securing members.
[00160] Figure 34 shows a perspective view of a bark collar or bark collar
unit 3400 under an
embodiment. Figure 34 shows metal electrode probe 3410 which is analogous to
metal probes
208 as shown in Figures 23A and 23B. Under the embodiment shown in Figure 34,
metal
electrode probe 3410 is configured to contact a skin surface of an animal
wearing the bark collar
unit 3400 and to detect vibrations generated by the animal's barking. Under
this embodiment, a
piezoelectric coupling located within the bark collar (as shown in Figures 35
and 36) facilitates
the bark collar's detection of barking events.
[00161] Note that the bark collar 3400 may comprise an integrated GPS
tracking/E-collar
system as described above with respect to Figures 19-33. Under this
embodiment, tracking and
stimulation units comprise discrete units and are removably coupled together.
However, the bark
collar may comprise a single collar component including metal electrode probes
3410. This
single collar component and corresponding circuitry may be dedicated solely to
bark detection
and stimulus delivery. Under this embodiment, the bark collar may use a
piezoelectric coupling
mechanism for monitoring and detecting metal electrode probe signals as
further described
below.
[00162] Figure 36 shows a side view of a bark collar unit 3600 under an
embodiment. Metal
electrode probe 3410 of Figure 34 corresponds to metallic electrode probe 3610
of Figure 36.
As seen in Figure 36, metal electrode probe 3610 comprises a metal electrode
probe tip 3614
and a metallic electrode probe insert 3612. The bark collar enclosure 3628
receives the metal
electrode probe insert 3612 in a receiving or mating cavity 3640. The metal
electrode probe tip
3614 is threadably secured to the metal electrode probe insert 3612. The metal
electrode probe
Page 28
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
insert 3612 comprises an upper surface 3630. This upper surface 3630
corresponds to the
electrode probe contact surface 3510 as shown in Figure 35.
[00163] Continuing with reference to Figure 36, the enclosure 3628 of the
bark collar
includes a receiving cavity 3640 for receiving the metal electrode probe 3610.
As indicated
above, the metal electrode probe 3610 may comprise a metal electrode probe tip
3614 and a
metal electrode probe insert 3612. The metal electrode probe is mated with the
receiving cavity
3640 as seen in Figure 36. Three elastomeric rings 3650 encircle the metal
electrode probe and
isolate it from the receiving cavity. Under one embodiment, the elastomeric
rings are removable.
Under another embodiment, the elastomeric rings are over-molded onto the metal
electrode
probe. These three rings provide the isolation under an embodiment.
[00164] Figure 35 shows in exploded view the components of a piezoelectric
coupling as
positioned within an enclosure 3514 of a bark collar under an embodiment.
Figure 35 shows
piezo bender retaining screws 3518, a piezo bender retainer 3516, a piezo
bender spacer 3520,
electrical contacts 3522, a piezo bender 3512, and metal electrode probe 3510.
[00165] Under an embodiment, the components of the piezoelectric coupling
are dimensioned
to collapse into a secured state (as further described below with respect to
Figure 36).
Continuing with reference to Figure 35, the piezo bender retainer 3516
comprises an inwardly
projecting rim around its upper inner periphery. The piezo bender retainer
3516 also includes an
inwardly projecting flange component 3524. The flange component 3524 comprises
two
openings for receiving and positioning the electrical contacts as further
described below.
[00166] It can be seen with reference to Figure 35 that the outer diameter
of the piezo bender
spacer 3520 is approximately equal to the interior diameter of the piezo
bender retainer 3516.
The diameter of the piezo bender 3512 is in turn approximately equal to the
outer diameter of the
piezo bender spacer 3520.
[00167] The retaining screws 3518 pass through openings in component 3526,
under an
embodiment. The floor of the bark collar enclosure 3514 includes screw bosses
3524 positioned
to receive piezo bender retaining screws 3518. The floor of the bark collar
enclosure 3514 also
Page 29
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
comprises three retaining feet 3530 under an embodiment. The retaining feet
are positioned to
secure and support the piezo bender 3512 as further described below.
[00168] Figure 36 is a side view of the bark collar unit 3600 and shows the
components of a
piezo bender coupling in a secured state. The retaining screws 3518 pass
through openings 3526
of the piezo bender retainer 3516 and are secured to corresponding screw
bosses 3524 in the
floor of the bark collar enclosure. In such state, the piezo bender spacer
3520, 3626 fits within
the piezo bender retainer 3516, 3624 with the outer surface of the piezo
bender spacer 3520,
3626 adjacent the inner surface of retainer 3516, 3624 and with an upper
surface of the piezo
bender spacer 3520, 3626 adjacent a lower surface of the retainer's (3516,
3624) inwardly
projecting retainer rim.
[00169] A lower surface of the piezo bender spacer 3520, 3626 contacts the
outer peripheral
surface of the piezo bender 3512, 3616 and presses the piezo bender onto the
retaining feet 3530,
3656. In the secured state, a lower surface of the piezo bender (not shown) is
pressably secured
to and in direct contact with metal electrode probe contact surface 3510,
3630. Further, electrical
contacts 3522, 3618 are in direct contact with an upper surface of piezo
bender 3512, 3616. The
openings in flange component 3524 both position and receive the electrical
contacts 3522, 3618.
The electrical contacts may comprise a spring. A secured state of the
piezoelectric coupling may
under an embodiment bias the spring with one end in contact with the piezo
bender 3512, 3616
and the other end in contact with a printed circuit board 3620 of the bark
collar's electrical
system.
[00170] The piezoelectric coupling described above enhances the accuracy
and ability of a
bark collar unit to prevent, discourage and/or to eliminate the occurrence or
frequency of a bark.
The piezoelectric coupling comprises a piezo bender which is coupled to a
mechanically isolated
metal electrode probe which is inserted into the enclosure of the bark collar
and makes physical
contact to the dog's neck when the bark collar is fastened around the dog's
neck with a collar.
[00171] When a dog wearing this dog collar barks, the neck vibration
generated by the bark is
transferred from the dog's neck to one end of the metal electrode probe and
again transferred
Page 30
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
through the metal electrode probe into a piezo bender which is in physical
contact with the other
end of the metal electrode probe.
[00172] As indicated above, elastomeric rings encircle the metal electrode
probe and isolate it
from the receiving cavity of the bark collar. Due to the mechanical isolation
between the metal
electrode probe and mating enclosure of the bark collar, the metal electrode
probe is free to
vibrate with little dampening from the mating housing. The isolated
configuration, i.e. the
isolation between the metal electrode probe and mating enclosure, operates to
prevent an
exchange of energy from the mating enclosure to the metal electrode probe.
This isolation
configuration provides a freedom of vibration across the metal electrode probe
and minimizes
spurious signals originating from excitation of the mating enclosure. This
vibration freedom
increases the sensitivity and magnitude of the vibration which is transferred
from the dog's neck
to the piezo bender. The intent of the "mechanical isolation" is to prevent
mechanical energy
applied to the mating enclosure from being seen by the piezo bender. The goal
is to ensure only
mechanical energy applied to the probe is seen by the piezo bender. This
reduces potential false
bark signal detection and wake up events, which extend the battery life of the
product.
[00173] Once the vibration of the dog's bark is transferred from the dog's
neck, through the
mechanically isolated metal electrode probe, and into the piezo bender, the
piezo bender vibrates
in response. This piezo bender vibration generates an electrical signal
proportional to the
frequency and magnitude of the coupled physical vibration and can be fed into
an electrical
system of a bark collar for processing.
[00174] The piezoelectric effect is the ability of certain materials to
generate an electric
charge in response to applied mechanical stress. One of the unique
characteristics of the
piezoelectric effect is that it is reversible, meaning that materials
exhibiting the direct
piezoelectric effect (the generation of electricity when stress is applied)
also exhibit the converse
piezoelectric effect (the generation of stress when an electric field is
applied).
[00175] When piezoelectric material is placed under mechanical stress, a
shifting of the
positive and negative charge centers in the material takes place, which then
results in an external
Page 31
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
electrical field. When reversed, an outer electrical field either stretches or
compresses the
piezoelectric material.
[00176] The piezoelectric effect is useful within applications that involve
the production and
detection of sound, generation of high voltages, and electronic frequency
generation. As
described above, the piezoelectric effect is critical to operation of the
piezoelectric coupling.
[00177] As indicated above, the vibration of the dog's bark is transferred
from the dog's neck
through the mechanically isolated metal electrode probe, and into the piezo
bender thereby
causing the piezo bender to vibrate in response. This piezo bender vibration
generates an
electrical signal proportional to the frequency and magnitude of the coupled
physical vibration.
The electrical system of the bark collar may include digital or analog signal
processing
components for detecting the occurrence of frequencies and/or magnitude values
which
correspond to bark events. The electrically equivalent signal created by the
excitation of the
piezo bender to mechanical energy is processed through a series of three
analog operational
amplifier stages. Stage one provides buffering and a ¨160Hz high pass filter.
The buffer
provides a high impedance input to match the high impedance output of the
piezo bender. The
filter eliminates low frequency content of the signals that are primarily
created from (non-bark)
movement and flexure that is picked up while the collar is worn. Stage two
provides unity gain
with variable attenuation that is updated and controlled by the bark detection
algorithm firmware.
If the signal is found to be very large in magnitude (using most of the
dynamic range of the ADC
(Analog to Digital Convertor)) the signal is attenuated in the second stage in
an attempt to
prevent clipping of the signal (a condition in which the input signal exceeds
the dynamic range
of the ADC). The third stage is a fixed gain stage to increase the overall
signal to optimally
conform to the electrical limits of the ADC with no attenuation from stage 2.
The overall set
point for the gain is a function of both the mechanical and electrical
characteristics of the entire
system. Finally, the conditioned signals from the three stage operational
amplifier AFE (analog
front end) are converted to a digital equivalent by using an ADC which is used
by the bark
detection algorithm for bark event detection.
[00178] Based on the outcome of the signal processing, the decision on
whether or not to emit
a correctional output to the dog is made. Correctional outputs may include but
would not be
Page 32
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
limited to an electrical stimulation, vibration, sound, or spray. Under one
embodiment, a bark
collar unit may comprise a user selectable switch that varies the level of
applied electrical
stimulus. A physical switch may allow user to select between various circuit
resistor values
and/or circuit networks which vary the current supplied to electrodes and/or
the on time of the
current (as controlled by pulse width modulation).
[00179] The bark control unit under the embodiment described above uses a
single
piezoelectric detection transducer to detect bark event signals. Under an
alternative embodiment,
a bark control unit may use two different bark detection transducers. The
first transducer
comprises a standard omnidirectional microphone and the second transducer
comprises a
piezoelectric element. During a bark event, the signal from the piezoelectric
transducer is used
to wake the microprocessor of the bark control unit from a low power state. In
turn, the
remaining bark event waveform is analyzed using the microphone. The dual
detection ensures
that the bark in question originated from the dog wearing the collar and not
another dog in close
proximity. The algorithm used by the microprocessor focuses primarily on the
attack envelope
characteristics of the acoustical waveform to identify or reject an event as a
valid bark. The
attack characteristic comprises the time it takes for the waveform signal to
proceed from zero or
silence to the peak amplitude.
[00180] The embodiment of the bark control unit otherwise described above
achieves a higher
level of signal fidelity using only a piezoelectric detection element. The
piezoelectric detection
described above improves the mechanical coupling between source of the bark
event and
detection circuitry of the bark control unit. The piezoelectric detection
described above operates
to reduce and/or eliminate filtering or dampening of the bark signal.
[00181] The algorithm for bark detection with respect to the piezoelectric
detection
embodiment described above analyzes the whole waveform to accept or reject the
event as a
bark. This improves both bark detection and false (non-bark) rejection.
[00182] The bark detection algorithm samples the signals from the ADC. A
number of
criteria are included as part of this method of discrimination. The algorithm
works to positively
detect a bark event on the basis of not being rejected by the following
criteria:
Page 33
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
[00183] Too Few Timeslots - This indicates a short duration event such as a
strike, a bump, or
a quick scratch or scrape. The bark detection algorithm identifies these
events and aborts as
quickly as possible in order to conserve battery charge. On the other hand, if
an early abort does
not occur due to a short duration event, then a single trigger event can cause
an increment of
more than one (possibly several) of the abort causes listed below. That is, a
possible bark can
fail the bark validation for more than one reason.
[00184] Abort Unsaturated Timeslots - This means that the signal amplitude
was too
high. Too many time slots were saturated; meaning there were too few
unsaturated timeslots to
properly analyze the signal for a bark. When used in conjunction with the
hardware attenuation
(stage 2) automatic gain control very few of these aborts should occur since
it results in a
decrease in the overall gain.
[00185] Abort Amplitude - This means that too few timeslots met the minimum
amplitude
requirement.
[00186] Abort Piezo Minimum Ratio and Abort Piezo Median Ratio - These
indicate that the
signal had features that made it look more like a scratch or a scrape than a
real bark. These tests
look at the ratio of the signal's absolute average voltage to its peak-to-peak
voltage in each
timeslot. Under one embodiment a single finding of a low ratio in one timeslot
is enough to
categorize the signal as a non-bark event. Real barks tend to have a higher
ratio than scrapes and
scratches, because real barks are produced by relatively soft tissue compared
to the hard plastic
of the enclosure.
[00187] Abort Piezo Low Pass Minimum Ratio and Abort Piezo Low Pass Median
Ratio -
These are very similar to the Abort Piezo Minimum Ratio and Abort Piezo Median
Ratio, except
that we first low pass filter the signal in firmware before we calculate the
ratio of the absolute
average voltage to the peak-to-peak voltage.
[00188] Abort Piezo Spike Ratio - This indicates that the peak-to-peak
amplitude of the signal
in one or more timeslots exceeded the average peak-to-peak amplitude of its
two neighboring
timeslots by a factor of > 1.75. That means that there was at least one spike
in the data, and
Page 34
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
spikes of that high an amplitude are uncharacteristic of a real bark. (Real
barks usually score
below 1.30).
[00189] Abort Piezo Absolute Spike Ratio - This indicates that the absolute
average amplitude
of the signal in one or more timeslots exceeded the absolute average amplitude
of its two
neighboring timeslots by a factor of > 1.75. That means that there was at
least one spike in the
data, and spikes of that high an amplitude are uncharacteristic of a real
bark. (Real barks usually
score below 1.30)
[00190] Not that the same bark detection method described above may be used
across a family
of bark detection collars that deliver varying forms of stimulus upon
detection of a bark event. In
other words, bark collar units may use the same bark detection method
described above
irrespective of whether the bark collar unit (i) delivers stimulus via
electrical probes, (ii) delivers
spray stimulus, (iii) delivers stimulus via ultrasonic blast, or (iv) delivers
stimulus in the form of
vibration.
[00191] Historically, bark detection has used positive logic. That is,
software (implementing
audio signal processing through analog or digital signal processing methods)
would test an
arbitrary waveform and if the criteria by which the waveform is evaluated is
met (was true), a
correction would be invoked, with the implication that the event is a bark.
[00192] The new approach for detection described herein uses negative
logic. Each waveform
is evaluated by a series of "tests" to prove that the waveform is not a bark.
Furthermore,
multiple tests have been created to allow greater discrimination of an
arbitrary waveform. If the
first test is true (i.e., if first test criteria are met indicating that the
waveform is not a bark) then
the negative logic process may abort. However, if the first test criteria are
not met, then negative
logic suggests that the waveform may be a bark. The waveform is then
reevaluated by the next
negative logic test. If the waveform passes through all of the tests (i.e.
failing to meet test
criteria), the implication is that the event was a bark. These additional
tests allow greater
discrimination of an event from previous designs to improve the confidence in
the waveform
identification since each additional test reinforces the negative logic and
thus further provides
that the waveform is a bark at the conclusion of all waveform test criteria.
Page 35
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
[00193] In addition to the improved confidence in the detection algorithm,
negative logic
minimizes power. The order of the negative logic test criteria was chosen in
such a way such
that the most frequently created non-bark waveforms (those created by bumps,
strikes, impacts,
etc.) would be detected first (aborting any further checks for that waveform)
and the unit quickly
returns to a low power state.
[00194] The bark detection unit may include user selectable sensitivity
ranges. The different
sensitivity settings change the levels of specific negative logic tests which
in turn, result in either
a broader range of waveforms in which a correction will be triggered or a
narrower range.
[00195] The bark detection unit can identify other dog vocalizations
(whining, whimpering,
moaning) to be detected/corrected in addition to barks.
[00196] The ratios and tests set forth above are applied to a waveform
(potential bark event)
using negative logic. The application of method allows for multiple testing
criteria to be
conducted and sequenced in such a way so as to maximize battery life. For
example, the criteria
of [176] has been found to be associated with an impact of the enclosure (a
frequent non-bark
event) and is selected as the first negative logic test.
[00197] The use of ratios and test as set forth above further allows the
algorithm to extend its
detection capabilities to include whines, whimpering and moans in addition to
barks.
[00198] The use of ratios and tests as set forth above allows for fixed
limits to be set while
using a variable gain system. Without the use of ratios the limits would need
to be modified
every time the gain of the AFE (Acoustic Front End) is changed.
[00199] A user may, through the display and the user interface, change the
limits of the
detection criteria (set forth in the ratios and tests above), thus making a
change that includes, but
is not limited to, the detection performance, selectivity and sensitivity of
the bark detection
algorithm.

[00200] The concepts and techniques disclosed herein are not limited to the
tracking and
control of animals, and could be applied to various other applications and
objects, without
departing from the scope and spirit of the present general inventive concept.
For example,
although the description discusses a dog collar worn by a dog, the present
general inventive
concept is not limited to any particular type of animal, and further may be
used by a human or
mechanical mobile subject.
[00201] Figure 37 shows a bark collar sensor mounting under an embodiment.
The exploded
view of Figure 37 shows a printed circuit board assembly (PCBA) 3702. The PCBA
receives
electrical signals from the piezoelectric vibration sensor. Figure 37 also
displays the piezo 3704
that is used as the vibration sensor. Figure 37 shows a grommet component 3706
that captures
the piezoelectric sensor with an undercut configuration. The grommet component
locates the
piezo directly to an underside of the PCBA. The grommet component also locates
to another
featured shape on the housing as seen in Figure 37 (3730) and Figure 38
(3806). An eclip 3708
receives (and captures) the probe insert 3710 as further shown in Figure 38.
[00202] Figure 38 shows a cross sectional view of a bark collar sensor
mounting under an
embodiment. Figure 38 shows a location of the printed circuit board 3802. A
grommet 3816 fits
directly to PCBA for vertical location of the piezo in stackup configuration
3818. The grommet
3816 features a protrusion element 3714 (as seen in Figure 37) configured to
contact or reside
directly adjacent the PCBA surface without disturbing PCBA components.
Accordingly, the
protrusion element 3714 may assume various configurations to accommodate
varying PCBA
surface configurations or alternative contact locations.
[00203] The piezoelectric sensor 3804 fits within the grommet. Under one
embodiment, the
piezoelectric sensor enters the grommet through an opening on side 3720 of the
grommet. The
opening is not seen in Figure 37; however the opening 3820 is readily visible
in Figure 38. The
outer periphery of the piezoelectric element resides immediately adjacent an
undercut lip of the
grommet as seen in Figure 38. The flexible grommet holder 3816 provides a
constant force on
the piezo to ensure contact between the piezoelectric sensor and the metal
probe. The grommet
3816 (i.e., the undercut feature) provides a slight interference fit 3812 with
the piezoelectric
sensor. As indicated above, the grommet locates on a feature of the plastic
housing 3806. Here
Page 37
CA 03050464 2019-07-16
WO 2018/132797 PCT/US2018/013737
the lower portion of the grommet mates with an upwardly extending annular
feature 3730.
Figure 38 shows a probe insert section 3810 of metal electrode probe. The
probe insert
comprises elastomeric rings to mechanically isolate the metal electrode probe,
i.e. to isolate
vibration and provide a hermetic seal. The piezo senses vibrations of the
metal electrode probe
and generates a corresponding electrical signal. The piezo connects to the
PCBA via wire 3830.
Accordingly, electrical signals generated by the piezo are communicated to the
PCBA.
[00204] The apparatus described above with respect to Figures 35-36
features an isolated
holder, rubber ring, and 2 screws which locate and hold the piezo into place.
An alternative
embodiment eliminates these screws and the holder and replaces these parts
with the inherent
shape of the molded flexible (rubber) grommet (shown in Figures 37 and 38).
The grommet
locates to the PCBA and a feature on the housing (as shown in Figure 38).
Screws which are
used to fix the PCBA are also used to compress the rubber grommet.
[00205] Using a rubber grommet provides more compression distance and
provides reduced
likelihood that the stack-up causes an issue with intolerable force to the
piezo (which could result
in damage and reduced functional reliability).
[00206] Figure 39 shows in exploded view the components of the
piezoelectric coupling as
seen in Figure 35 with the addition of a damping element 3910, under an
embodiment. One
embodiment of the piezo electric coupling includes a dampening element on the
underside of the
piezo. The damping element may reside between the piezoelectric element and a
surface of the
metal electrode probe. Under this embodiment, this dampening element is in
direct contact with a
surface of the metal electrode probe. Figure 40 shows in exploded view the
